3 Claims. (Cl. 20-12) This invention relates to windows of the double hung type in which a pair of sash members are mounted to slide in a suitable frame member fitted into the window opening. In windows of this type the sash members, of course, are usually arranged to move upwardly and downwardly and, when the window is closed, the lower sash is generally the inner sash and the upper sash is generally the outer sash.

The principal object of the invention is to provide a simple, inexpensive and effective construction for holding the sashes in any desired position of vertical adjustment as well as to secure weather tightness when the window is closed. Another important object is to provide a construction for the purpose described which is easy to manufacture, install and maintain. A still further objective is to provide a construction which will not rattle when the wind blows while at the same time avoiding all possibility of binding the sashes and thereby insuring easy movement thereof. More specifically, it is an object of the invention to provide a construction wherein the parting bead between adjacent sashes is constructed with yielding means adapted to exert pressure against the sashes in order to maintain tightness, prevent rattling or binding and, at the same time, hold the sashes in any desired position of vertical adjustment.

How the foregoing objectives and advantages together with such others as may appear hereinafter or are incident to my invention are attained is illustrated in preferred form in the accompanying drawings wherein:

Fig. 1 is a partial vertical section through a window embodying my improvements taken approximately as indicated by the line 1--1 in Fig. 2 with certain portions of the structure shown in elevation;

Fig. 2 is a plan section taken approximately as indicated by the line 2-2 in Fig. 1;

Fig. 3 is a partial sectional elevation of the inside of the window taken approximately as indicated by the line 3--3 of Fig. 1; and

Fig. 4 is a very much enlarged fragmentary plan section taken approximately as indicated by the line 4--4 on Fig. 1.

In the drawings I have illustrated the head member 5 and one jamb member 6 of the window frame. These may be of any familiar construction and may, if desired, be provided with suitable inner facing strips 7 and 8. The upper sash of a double window is shown at 9 and the lowersash at 10. All of the parts so far mentioned are of familiar design and form no part of the present invention. It will be understood, of course, that only one side of the window with its jamb 6 is illustrated in the accompanying drawings because the other side is a mere duplicate.

My invention involves the use of a vertically extending facing strip 11 which can be secured in any desired manner to the adjacent jamb member 6. In the embodiment illustrated this facing member takes the form of a onepiece sheet metal member having a vertically extending mid-rib 12 and a pair of'sash embracing ribs 13 and 14 at each side thereof. As best seen in Figures 2 and 4 these ribs are formed by suitably bending the metal of the facing strip, the sash embracing ribs 13 and 14 being relatively shallow while the mid-rib 12 extends inwardly a substantial distance for a purpose which will appear below. However, it should be understood that these ribs can be formed in other ways, as by an extrusion procedure or by aflixing the ribs to the plate.

At its inner edge the mid-rib is provided with oppositely extended flanges 15 which parallel the face of the strip 11 and form with the face a vertically disposed troughlike recess 16 on each side of the rib 12, one of which recesses faces the sash 9 and the other the sash 10. Along the outer edge of each mid-rib flange 15 I provide a reentrant rib 17 which is arranged in direct opposition to the inner rib 13 of each sash embracing pair of ribs.

Within each trough-like recess 16 I provide a vertically extending channel member 18 having its base against the adjacent sash and its legs 18a extending toward the midrib. The end of each leg 18a is provided with a foot-like motion limiting flange 18b. (See Fig. 4.)

At a plurality of points vertically of the mid-rib 12 I provide flat horizontally arranged slots or apertures in which I mount a series of substantially V-shaped springs 19, the legs of which press against the adjacent face of the base portion of the channels 18 as clearly shown in Figs. 1 and 4. As will be appreciated by those skilled in this art the mid-rib construction which I have devised constitutes a parting bead which has a yielding face at each side adapted to press against the face of the adjacent sash.

At this point I wish to call attention to the fact that the sashes 9 and 10 are loosely embraced by the pairs of ribs 13 and 14 so that they do not rub against the ribs 13 when the parts are assembled. This is best shown in the greatly enlarged illustration of Fig. 4. In other words, the sashes move up and down against the floating channel member 18 of the parting bead so that all possibility of binding is avoided. At the same time, sufficient pressure is exterted by the springs 19 to cause the channels 18 to hold the sashes in any desired position of vertical adjustment. Simultaneously, of course, the structure acts as a very adequate weather stripping. The foot-like, motion-limiting flanges 18b are arranged to engage the flanges 13 and 17 so that the channels are prevented from falling out of the recesses 16 in case of ex cessive looseness or removal of a sash. In assembling the parts the channel members 18 are slid into place from either the top or the bottom before the structure is placed into the window frames.

I claim:

1. For a window opening having frame jambs and a pair of sash members slidable therein; the combination of a vertical facing strip adapted to be secured to a jamb, said strip having a vertically extending mid-rib adapted to project inwardly between the sash members, said rib having oppositely extended flanges paralleling the facing strip and forming with the facing strip a vertically disposed, trough-like recess on each side of the rib, a vertical channel member fitting each recess with its legs projecting toward said rib and its base arranged to contact the face of the adjacent sash member, and a plurality of spaced springs housed in the recesses and channel members and adapted to urge said channel members into frictional contact with the sash faces.

2. A window structure according to claim 1 wherein the facing strip is provided with a sash embracing rib at each side of said mid-rib and wherein a remnant rib extends along the outer edge of each mid-rib flange in opposition to the inner rib of each sash embracing pair Patented 12, 1959 3 of ribs, and, further, wherein each leg of each channel member is provided with an outwardly extending motion limiting flange.

3. A window structure according to claim 2 wherein the springs are substantially V-shaped and disposed in 5 slots in the mid-rib with one leg of each spring pressing against the base of the adjacent channel member.
